}

2 Modelclass :

@Getter
@Setter
public class TestModelDTO {

    private String name;
    private String address;
}

Test Repositry Interface

@Repository
public interface TestRepository extends ElasticsearchRepository<TestRepositoryModel, String>{

    public TestRepositoryModel findByName(String itemId);
}

4. TestRepositoryModel class

@Data
@Builder
@AllArgsConstructor
@NoArgsConstructor
@Document(indexName = "#{@environment.getProperty('test.model.project.index')}")

public class TestRepositoryModel {

    @Id
    @Field(type= FieldType.Keyword)
    private String id;

    @Field(type= FieldType.Keyword)
    private String name;

    @Field(type= FieldType.Keyword)
    private String address;

}

When i start the server i am getting the below error

we tried below solution as temporary fix as elastic cluster upgrade to 8.16: https://www.elastic.co/guide/en/elasticsearch/client/java-rest/current/java-rest-high-compatibility.html

but we are moving elastic client as permanent fix. Can anybody please suggest solution for above error.
